Règlements de sécuritéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The author discusses the guidance papers the Association has published to assist companies in the supply chain to meet safety standards.
Food contact materials (FCMs) are widely used in packaging for every day fonds and beverages. Whereas kitchen ustensils tend to corne into contact with foods only briefly, food packaging allows food to be stored for long periods, which means extended contact can coeur. Adhesives are used in almost all food packaging, to bond the different materials used but direct food contact is rarely intended.
Adhesives typically make up less than 5% of food packaging and, for most adhesive applications, direct food contact is not intended.
The adhesives industry is working hard to ensure that its products are safe. FEICA, the Association of the European Adhesive & Sealant Industry, has published several guidance papers to help not only their own members but also the other players of the FCM supply chain, to ensure that the final packaging is safe.

ChitosaneLe chitosane ou chitosan est un polyoside composé de la distribution aléatoire de D-glucosamine liée en ß-(1-4) (unité désacétylée) et de N-acétyl-D-glucosamine (unité acétylée). Il est produit par désacétylation chimique (en milieu alcalin) ou enzymatique de la chitine, le composant de l'exosquelette des arthropodes (crustacés) ou de l'endosquelette des céphalopodes (calmars...) ou encore de la paroi des champignons. Cette matière première est déminéralisée par traitement à l'acide chlorhydrique, puis déprotéinée en présence de soude ou de potasse et enfin décolorée grâce à un agent oxydant. Le degré d'acétylation (DA) est le pourcentage d'unités acétylées par rapport au nombre d'unités totales, il peut être déterminé par spectroscopie infrarouge à transformée de Fourier (IR-TF) ou par un titrage par une base forte. La frontière entre chitosane et chitine correspond à un DA de 50 % : en deçà le composé est nommé chitosane, au-delà , chitine. Le chitosane est soluble en milieu acide contrairement à la chitine qui est insoluble. Il est important de faire la distinction entre le degré d'acétylation (DA) et le degré de déacétylation (DD). L'un étant l'inverse de l'autre c'est-à -dire que du chitosane ayant un DD de 85 %, possède 15 % de groupements acétyles et 85 % de groupements amines sur ses chaînes.
Le chitosane est biodégradable et biocompatible (notamment hémocompatible). Il est également bactériostatique et fongistatique.
Le chitosane est également utilisé pour le traitement des eaux usées par filtration ainsi que dans divers domaines comme la cosmétique, la diététique et la médecine.

Tests microbiologiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : The antimicrobial properties of two disparate bio-based coating additives were evaluated in a polyvinyl alcohol (PVA) food packaging coating for antimicrobial activity. Chitosan, a shrimp and crustacean shell derived polysaccharide, and an antimicrobial peptide were evaluated in a dissolvable food package coating for reductions in microbial growth after contacting agar patties serving as food simulants. Where the antimicrobial components of such packaging coatings are chosen to be generally recognized as safe by worldwide regulatory agencies, migration from the packaging into headspaces and food-contact surfaces can provide enhanced efficacy against foodborne pathogens, including viruses. The techniques and coatings presented in this article suggest that dramatic improvements in food safety can be achieved using coatings containing non-toxic bio-based biocides.

- Fig. 4 : Dose responses of chitosan and AMP7, individually and in combination. The percent growth inhibition (as determined by reduced colony counts compared to PVA negative control) was used to calculate the dose response to coatings dosed with varying concentrations of AMP7 (A) and chitosan (B). A heatmap shows the response (as percent growth inhibition) to numerous combinations of different concentrations of AMP7 and chitosan (C).

Polyéthylène basse densitéIndex. décimale : 667.9 Revêtements et enduits Résumé : In the present study, silver nanoparticles were biosynthesized using banana (Musa spp.) peel extract as the reducing agent. The biosynthesized particles were then characterized using scanning electron microscopy, X-ray diffraction, transmission electron microscopy and Fourier transform infrared spectroscopy. Biosynthesized silver nanoparticles were then evaluated for their antibacterial activity against Gram-positive and Gram-negative cocci bacteria through agar diffusion study and minimum inhibitory concentration, and minimum bactericidal concentration was determined. Low density polyethylene film was coated with the biosynthesized silver nanoparticles following the dip coating method. The nanoparticle incorporated polymer films were then evaluated for antibacterial and antioxidant activity by agar diffusion studies, dynamic shake flask studies and 2, 2- diphenyl-1-picryl-hydrazyl-hydrate free radical scavenging assay, respectively. The surface characterization of the prepared films was also performed to ensure the presence of silver nanoparticle coating.
